Fibromyalgia causes widespread pain and is not curable.

In 2016, Lady Gaga revealed an Instagram post is 2016 that she suffers from "chronic pain" but never gave more details. But in her upcoming documentary, "Gaga: Five Foot Two," the singer and actress dives a little deeper into the disease she's been battling for some time.

The singer recently tweeted that the chronic pain she deals with is fibromyalgia, a disorder that is more common than people may think. In the tweet, she wrote that she wants to, " help raise awareness and connect people who have it," CNN reports.

Fibromyalgia is a chronic pain disorder that causes tenderness to touch or pain over the body.

According to the National Fibromyalgia & Chronic Pain Association, the disease can vary in intensity and affects people "physically, mentally, and socially." People suffering from this disorder, which often manifests itself in adolescence or young adulthood, feel more pain than would be typically expected. Because of this pain, a few common symptoms include fatigue, tenderness, sleep disorders, memory problems, depression, and stiffness.

The foundation also reports that 10 million Americans suffer from fibromyalgia with a ratio of eight to two ratio, women over men.

Healthline reports that treatment typically goes beyond medication and focuses on improving quality of life through self-care and lifestyle changes. Medication options vary from antidepressants and sleep aids to pain relievers and narcolepsy drugs.

In addition to Gaga, Morgan Freeman has specifically spoken about dealing with fibromyalgia. In an interview with Esquire, the actor described the pain. "Up and down the arm," he said. "That's where it gets so bad. Excruciating." The actor doesn't let this pain stop him from doing some of the things he enjoys like golfing or walking, but he can't fly pilot jets or drive.

According to ABC, other stars that have suffered from chronic pain include Paula Abdul, George Clooney, and Tobey Maguire.

In a press conference, Gaga said that the "pain is a microphone" and it "does me no good unless I transform it into something that is," Variety reports. Here's hoping "Gaga: Five Foot Two," which will be available on September 22 on Netflix, inspires others suffering to transform the pain.
